“It was a very unusual case. It’s disturbing and gruesome.” Troy Oviatt, with the Fairfield Police Major Crimes Unit, told FOX40.

Police say it didn’t take long to zero-in on the father of the boy, 18-year-old Joshua Cooper. He was arrested for allegedly biting off a third of his son’s nose because the child wouldn’t stop crying.

“I have a three-month-old and a two-year-old. You get frustrated,” neighbor Ashley Payne said. “To harm your child like that, I don’t see how anyone could do that.”

Neighbors say they don’t personally know Cooper.

The infant also suffered from a skull fracture and brain hemorrhaging.

The child is being treated at Oakland Children’s Hospital. As for Cooper, he’s charged with child endangerment and aggravated mayhem.

Police will continue to investigate how the infant sustained the other injuries.
